Selective membrane may cycle dual-ion batteries closer to reality

Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries—right? Not quite. The rocking-chair mechanism that allows for commercial power storage ...

Chemists create nanoparticles for safe imaging of tumors

Chemists from Russia and Switzerland created biosafe luminescent nanoparticles for imaging tumors and blood vessels damaged by heart attack or stroke. The particles are made of hafnium oxide that is used for intravenous injection, ...

Simple separation process for neodymium and dysprosium

Rare-earth metals are critical components of electronic materials and permanent magnets. Recycling of consumer products is a promising source for these rare commodities. In the journal Angewandte Chemie, American scientists ...

Rare earth ions in a crystal become candidate for a quantum memory

(Phys.org) —A promising material is lining itself up as a candidate for a quantum memory. A team at the Max Planck Institute for the Science of Light in Erlangen is the first to succeed in performing high-resolution spectroscopy ...
